Mature transplants added to a woodland degraded by cattle grazing in Wisconin were "healthy" in the six years that the plants were monitored, and with low mortality; the authors did not report whether they reproduced (Ellarson and Craven 1982).

Transplants in a field study had 94% survival after 7 years. Wild geranium self-sows and can spread by seed once established (Mottle et al. 2006).

Seed output moderate; low vegetative spread (Barkely 1986, Gleason and Cronquist 1991).
